A2109 USB Host+OTGSupport

um, If you tell me what that means exactly I might be able to check it out on my A2109.

Nevermind, looked it up on wiki. Looks interesting I will try it out if I can get hold of a cable. Ahh seems there is a certified spec, I doubt Lenovo has that built in or they would be advertising it.
On the other hand it seems like we just need kernel support which some engineer could have slipped in I guess.
Hopefully we can get an unlocked bootloader, root etc... and then who knows...
